Brazilian Energetic Matrix

Renewable energy sources are those forms of energy production in which their sources are capable of remaining available for a long term, relying on resources that regenerate or remain permanently active. In other words, renewable energy sources are those that rely on non-exhaustible resources

Identify from the alternatives below which energy source is non-renewable

• Biomass

• Solar energy

• Wind energy

• Mineral coal

A country's energy matrix is made up of renewable and non-renewable energy sources. An example of a renewable energy resource is:

• oil.

   

• mineral coal.

   

• wind.

• natural gas.

 

Ethanol is one of the main elements that make up the energy matrix for transport in Brazil. It is classified as an energy source:

• renewable, like coal.

   

• non-renewable, like gas.

• renewable, such as biomass.

• primary, like oil.

• fossil, such as oil.

  In relation to the electrical matrix, that is, the one responsible for producing electrical energy, the main source used in Brazil is:

• wind.

   

• nuclear.

• hydroelectric.

• biomass.

• solar.

   The use of fossil fuels is widely criticized, especially worldwide, due to their contribution to

• reduction in contamination levels in the seas.

   

• attenuation of the thermal inversion phenomenon.

• decrease in the average terrestrial temperature.

• removal of vegetation from planted forests.

• increase in the emission of atmospheric pollutants.

1Which resource, among non-renewable resources, occupies the first position in terms of participation in the global energy matrix?

• Oil

   

• Natural gas

• Nuclear

• Mineral coal

• Biomass

Renewable energy sources are any resource that can remake itself or is not limited. Based on this information, renewable energy sources are listed below, except:

•  

  hydroelectric power

   

• natural gas

• wind energy

• solar energy

• biofuels

Non-renewable sources can be completely exhausted within variable periods of time (short, medium and long term) depending on extraction, consumption and availability.

 

Of the alternatives below, which one lists only renewable energy sources?

• biofuels, petroleum and mineral coal.

   

• solar energy, wind energy and uranium.

• uranium, natural gas and hydroelectric energy.

• hydroelectric energy, solar energy and biofuels.

• natural gas, wind energy and solar energy.

   This source of energy widely used in Brazil and around the world is a fossil ore that, when processed, gives rise to several by-products, such as gasoline, diesel oil, kerosene, in addition to generating electricity in thermoelectric plants.

 

What energy source does the fragment above refer to?

• Natural gas

   

• Sugar cane

• Mineral coal

• Oil

To solve the question, read the following text, about energy sources, and select the words/expressions that correctly and coherently fill in the gaps.

 

_____ was an important source of energy for the First Industrial Revolution. Currently, the largest reserves are in the _____ hemisphere. It is one of the main causes of _____, as its burning releases a large amount of sulfur oxide into the atmosphere.

• mineral coal — north — acid rain

• oil — south — ocean pollution

• oil — south — acid rain

• mineral coal — south-ocean pollution

• oil — north — acid rain
